MAMEWorld Forums - EmuChat - Re: dip settings for Gremlin/Sega N-Sub

Gremlin/Sega's N-Sub has been supported for some time. Besides the missing cobalt, blue colors still missing as well as audio effects, the dip switch settings have not been supported either as shown in source file http://mamedev.org/source/src/mame/drivers/vicdual.c.html

iirc Someone may have looked over N-Sub dip settings earlier, but wasn't able to determine how coin board worked with N-Sub's main logic board....that's what I vaguely remember many years earlier. More vicdual hardware type dips settings later for this thread.

If wondering what exact colors should look like, here is an N-Sub flyer for reference. http://flyers.arcade-museum.com/?page=thumbs&db=videodb&id=2739

It appears all the roms for upright cab have been dumped, so it would be someone that can tell how video output for this game should work is still needed.

Fortunately, the Japanese version of N-Sub manual is online and it does have dip switch settings. The uploaded, scanned page of dip settings was extracted from the N-Sub pdf file that Al K. scanned many years earlier when he was running Wiretap.

The 8 position dip swich is on a add-on pcb described as a coin calculator and part number is listed as 97201-P. It only deals with coin credits for handling coin inputs in both coin chutes. No other dip switches involved with N- Sub.
